DRUM.

Application led ctoher 5, 1923. Serial No. 666,792,

lIhis invention relates to drums, andan object of the invention is to provide a simple, practical and durable'structure for securely clamping the drum head in proper position upon the shell, which construction will eliminate the many inconveniences contingent with the use of flesh hoops.

In the present approved constructions oit' bass drums, snare drums, tympani, tom toms, and the like, the flesh head of the drum is rolled about the flesh hoop and tightly stretched, after which the hoops are placed in position and clamped either by metallic or rope clamp structures, and it requires an experienced and skilled operator to properly wrap the edges of the head about the flesh hoop, and also requires considerable time, making this a comparatively expensive operation and causing considerable inconvenience to drummers when it is necessary to replace a head.

It is an object of the present invention to provide a novel construction for clamping the head in place which eliminates the iiesh hoop and the inconveniencesy contingent therewith, and will enable a drummer to quickly and easily replace a worn or broken head.

Other objects of the invention will appear in the following detail description 4and in the accompanying drawings wherein:

Figure l is a perspective view of the improved drum.

Figure 2 is an enlarged detail section taken on the line 2-2 of Figure l.

Referring more particularly to the drawings, a bass `drum is shown in the drawings, however, it is to be understood that the present invention is applicable for use on snare drums, tympani, tom-toms, or analogous drums, without departing `from the spirit of this invention. The drum includes the shell l which is circular in cross section, as is usual in Vdrum construction, and it comprises the heads 2 which are formed of the usual material of which drum heads are made. In placing the heads 2 on a drum, it is the general practice to dampen the heads, allowing them to be stretched over the shell and when they dry, the heads con- 5G tract and provide the tautness desired. The

present drum structure includes a head band or hoop 3 which may be constructed of any suitable material and which has a longitudinally extending groove l in its Vouter c5 surface, preferably formed inwardly towards its inner edge.` In assembling the drum structure, the iiesh head 2 is stretched over the edge of the shell l, across beneath the inner edge of the head hoop 3 and along the outerside of the hoop 3 to the groove 4l, and across the grooveas clearly shown in Figure 2 of the drawings. A clamping band 5 is placed within the groove 4 against the outer surface of the edge of the flesh head 2 of the drum and the band 5 is tightly clamped in place through the medium of suitable clamping screws 6 and the angled Y e clamping members 7 which are placed at the meeting ends of the clamping band 5.

The head bands or hoops 3 are tightly clamped in place on the edges o1c the shell l by means of the clamps 8, the tension hooks 9 of which engage over the outer edges of the hoops, and the thumb rods 10 which extend through the clamps 8 and thread into the heads ll carried by the rods 13.

From the foregoing description, taken in connection with the accompanying drawings, it will be apparent that a' flesh head of a drum may be quickly and easily replaced or placed in position, with a minimum of inconveniences through the use of the improved head and clamping bands and that the many inconveniences contingent with the use of what is commercially known as the flesh hoop will be eliminated.

What I 'claim is:

A drum comprising a cylindrical shell of interconnected arcuate sections including a pair of drum heads and retaining hoops therefor and normallypositioned on each open end ot'said shell, said hoops each provided with an annular groove in their pe-V ripheries and adjacent the inner edges there- 95 of, the circumferentially formed edges of said drum heads disposed over the edges ci said shell and turned outwardly over the inner edges of said hoops and partly disposed in said annular grooves, an adjustable clamping band disposed in each of said grooves for securing the edges of vsaid drum heads carried by said hoops, a plurality of circumferentially spaced and slotted ears formed on the outer surface of said hoops lVILLIAM A.
